Water hammer occurs when a valve closes rapidly, stopping the flow of water abruptly. This action causes a pressure wave to travel through the pipe, causing pressure fluctuations that can be very high. These shock waves can lead to different problems:â£
â£
ð——ð—®ð—ºð—®ð—´ð—² ð˜ð—¼ ð—¶ð—»ð—³ð—¿ð—®ð˜€ð˜ð—¿ð˜‚ð—°ð˜ð˜‚ð—¿ð—²: pressure fluctuations can cause ruptures in pipes, joints and other system components. This not only entails repair costs, but also interruptions in water supply.â£
ð—˜ð—³ð—³ð—¶ð—°ð—¶ð—²ð—»ð—°ð˜† ð—¹ð—¼ð˜€ð˜€: water hammer can cause water and energy losses, affecting the overall efficiency of the system.â£
ð—¦ð—®ð—³ð—²ð˜ð˜† ð—¿ð—¶ð˜€ð—¸ð˜€: In industrial and urban installations, water hammer can represent a safety risk for operators and people in the vicinity of the affected installations.â£

To prevent and mitigate water hammer, several strategies and devices are used, including the use of backflow preventers. These systems allow water to flow in one direction only and prevent the sudden return of fluid, thus reducing the chances of water hammer.â£
â£
ð—¦ð—¼ð—³ð˜-ð—°ð—¹ð—¼ð˜€ð—² ð˜ƒð—®ð—¹ð˜ƒð—²ð˜€: prevent abrupt changes in system pressure by providing an operation that allows a smooth transition between open and closed positions. This can be achieved with pressure reducing valves or with electric or pneumatic actuators.â£
ð—”ð—¶ð—¿ ð—¿ð—²ð—¹ð—²ð—®ð˜€ð—² ð˜ƒð—®ð—¹ð˜ƒð—²ð˜€: the elimination of air in the installation significantly reduces the overpressure generated by water hammer, reducing its consequences.â£
ð—–ð—µð—²ð—°ð—¹-ð˜ƒð—®ð—¹ð˜ƒð—² ð—°ð—¼ð˜‚ð—½ð—¹ð—¶ð—»ð—´ð˜€: such as Hidroten's ð—°ð—µð—²ð—°ð—¸- ð˜ƒð—®ð—¹ð˜ƒð—² ð˜€ð˜ð—¿ð—®ð—¶ð—´ð˜ð—µ ð—°ð—¼ð˜‚ð—½ð—¹ð—¶ð—»ð—´ð˜€, these systems not only prevent water hammer, but also prevent the lines from emptying, which facilitates the start-up of the system.â£
